SEALING-CAP FOR BOTTLES.

To all whom it may concern: Be it known that we, EVERETT DoUGnAs BETTS,a subject of the King of Great Britaln, and EDWARD VANDENBERG, a citizenof the United States, and both residents of I iancaster, in the countyof Erie and State of New York, have invented a new and Im rovedSealing-Ca for Bottles, of which the ollowing is a ful clear, and-exactdescription.

In putting up sealed packages for1 the trade, of soft drinks such asbeer, ale, mineral waters and carbonatedliquids, the bottles containingsuch liquids are sealed at the bottling works by machinery, and when theclosures of such receptacles are removed, no means for sealing thebottles again to preserve air tight any of the contents that may remainin the bottles, are provided, conseuently the beverage becomes stale anddat and therefore unfit for liquid refreshment.

The object of our invention is to provide ay novel, simple sealingcapfor bottles, that may be readily applied to the openneck of Vabottle, and hermetically seal the breached receptacle for thepreservation of any contents of the bottle that may remain after thebottle has been first opened and a p ortion of the liq'uid thereinremoved.

The invention consists in the novel construction and combination ofparts, as is the appended claims.

Reference is to be .had to the accompanying drawings forming a part ofthis speciiiy cation, in whichsimilar characters of reference indicatecorresponding parts in all the vlews.

Figure 1 is a side view of a bottle neck, and of the improved sealingcap ,mounted thereon; Fig. 2 is a transverse sectional view of theimproved sealing cap applied as a closure upon a bottle neck, and ig. 3is a perspective view of the improved sealing cap, detached,

and exposing its novel construction.

The improved sealing cap is preferably made of non-corrodible metal,such as aluminum, and may with'advantage be cast .into form.

The device consists of an imperforate disk 5 rounded on the' periphery,and having a eripheral flange 5a that projects below the at lnnersurface thereof sufficiently to form a'shallow recess, wherein'isembedded a flat circularly edged lanchet 6 of rubber, or other slightlyyiel ing material. Integrally Spcification of Letters Patent.

lclaim* as new and desire to Patented May 5, 1908.

with the flange 5, two flanged' extensions 5b are formed oppositelythereon, each having a slo ed free edge which extends from theperipheral flange 5a to an ol'set shoulder a, said shoulders being of anequal height and disposed o positely. Upon the sloped edges of the angedextensions 5b, an inwardly turned hook flange 5C is formed on each, asappears in Figs. 2 and 3.

The improvement is designed to be mounted upon a class of bottles usedfor the packing of malt and aerated beverages. Usuallyl these bottleshave similar necks 7, that, at their pouring ends, each terminate in aradial bead 7 a, shown in Figs. 1 vand 2.

The hook flanges 5c are spaced apart at the shoulders a on the flangedextensions 5b, a distance that ermits them to be slid into engagementwith) the bead- 7 a at opposite points thereon. This is effected by`first imposing the joint planchet 6 upon the free edge of the bottleneck 7 opposite the shoulders a, and then pressing the cap piece 5 indirection of this arrow in Fi 1, which will forcibly impin e the hook'anges 5c upon the lower side of t e'radial bead 7a.

It will be seen that the sliding engagement of the cap piece, ashereinbefore' described, will compress the elastic joint planchet 6 uponthe true top edge of the bottle neck 7 and-thus seal the samehermetically, holdin the Ifgaseous and liquid contents therein unti theottle is breached by a removal of the cap piece. y It is claimed that byemployment of the improved sealing cap, a great saving of the liquidycontents of beer, ale, or soda water 'bottles may be eected, as uponremoval of the corks first holding the bottle necks sealed,

and a removal of a por-tion of the contents of the bottles, theremaining gas and liquor may bepreserved for subsequent use by quicklylacing the improved sealing cap upon the bottle neck.

Having thus described our invention,'we secure by Ii'etters Patent; Y f

1. A sealing cap for a bottle neck, comprising a' circular disk, aperipheral flange thereon, two qqpposite depending flangesy on theperipheral ange and having sloped edges that are turned inward forminghook members thereon, and a pliable joint'piece on the disk held-inplace by the peripheral flange.

2. A sealing. cap for a bottle neck, comlprising a fiat circularly'edgeddisk, an inte-v Y:lo

gral peripheral flange on one side ofthe disk, tWo op osite fiangedextensions on the pe` riphera flange, said flanged extensions havmgsloped lower edges that are turnedinwardly producing hook membersthereon, one end of each depending flange merging into' the peripheralflange and the other end thereof 'terminating in an offset shoulder,anda pliable joint piece seated on the disk and contacting with theperipheral flange.

3. The combination with a bottle neck,

having an annular bead at its pourin end, of

a sealing cap comprising a flat cireu ar disk, an' integral dependingperipheral flange on said dis depending flanged extensionsoppositelywdis osed. on the eripheral `flange, each flange aving a slopeedge, said ed es inclining toward the same point on the expending,flange and having/inwardly bent members thereon, that form hooks thatmay 20 f EVERETT 'DoUGLAs BETTS.
